Rehabilitation activities include removal and replacement of existing inside and outside shoulders, guardrails, rumble strips, drainage inlets, and dikes, and installation of oversized drains. The proposed project will also involve upgrades to ramp facilities for ADA compliance, installation of two temporary detour lanes in the existing median, extension of existing rock slope protection (RSP) at 44 bridge locations, and hydroseeding the median for erosion control and vegetation restoration. Determination This proposed Mitigated Negative Declaration (MND) is included to give notice to interested agencies and the public that it is Caltrans’ intent to adopt a MND for this project. This does not mean that Caltrans’ decision regarding the project is final. This MND is subject to change based on comments received by interested agencies and the public. Caltrans has prepared an Initial Study for this project, and pending public review, expects to determine that the proposed project would not have a significant effect on the environment for the following reasons: The proposed project would have no impact on aesthetics, agricultural and forest resources, air quality, geology and soils, hazards and hazardous materials, land use and planning, mineral resources, noise, population and housing, public services, recreation, transportation/traffic, tribal cultural resources, or utilities and service systems. The proposed project would have less than significant impact on cultural resources, and hydrology and water quality. The proposed project would have less than significant impacts with mitigation on biological resources. To avoid and/or minimize potential impacts to biological resources, the following measures will be implemented. WQ-1: Construction General Permit. Prior to commencement of construction activities, the contractor shall obtain coverage under the State Water Resources Control Board’s National Pollutant Discharge Elimination System (NPDES) General Permit for Storm Water Discharges Associated with Construction and Land Disturbance Activities (Construction General Permit), Order No. 2009-0009-DWQ, as amended by 2010- 0014-DWG and 2012-0006-DWQ, NPDES No. CAS000002, or any other subsequent permit. This shall include submission of Permit Registration Documents (PRDs), including Notice of Intent (NOI) for coverage under the permit to the State Water Resources Control Board via the Stormwater Multiple Application and Report Tracking System (SMARTS). Construction activities shall not commence until a Waste Discharge Identification Number (WDID) is obtained from SMARTS. A Storm Water Pollution Prevention Plan (SWPPP) shall be prepared and implemented to address all construction-related activities, equipment, and materials that have the potential to impact water quality. WQ-2: Caltrans MS4 Permit. The contractor shall comply with the provisions of the National Pollutant Discharge Elimination System (NPDES) Permit, Statewide Storm Water Permit, Waste Discharge Requirements (WDRs) for the State of California, Department of Transportation Order No. 2012-0011-DWQ (Caltrans MS4 Permit), as amended by Order No. 2014-0006-EXEC, Order No. 2014-0077-DWQ, and Order No. 2015-0036-EXEC, NPDES No. CAS000003, or any subsequent permit. Caltrans- approved Design Pollution Prevention BMPs and Treatment BMPs shall be implemented to the maximum extent practicable (MEP), consistent with the requirements of the Caltrans MS4Permit. BIO-1: Biological Monitor. An authorized contractor supplied biologist will be designated to oversee compliance of all protective measures and will monitor all construction-related activities. The biological monitor will notify the resident engineer of project activities that may not be in compliance. The resident engineer will stop work until the protective measures are implemented fully. BIO-2: Worker Environmental Awareness Training. A qualified biologist will present to each employee (including temporary, contractors, and subcontractors) a worker environmental awareness training, prior to the initiation of work. They will be advised of the special status species in the project area, the steps to avoid impacts to the species and the potential penalties for taking such species. At a minimum, the program will include the following topics: occurrence of the listed and sensitive species in the area, their general ecology, sensitivity of the species to human activities, legal protection afforded these species, penalties for violations of Federal and State laws, reporting requirements, and project features designed to reduce the impacts to these species and promote continued successful occupation of the project area environs. Included in this program will be color photos of the listed species, which will be shown to the employees. Following the education program, the photos will be posted in the contractor and resident engineer office, where they will remain through the duration of the project. The contractor, resident engineer, and the qualified biologist will be responsible for ensuring that employees are aware of the listed species. If additional employees are added to the project after initiation, they will receive instruction prior to working on the project. BIO-3: Materials and Spoils. Project materials will not be cast from the project site into nearby habitats and project related debris, spoils, and trash will be contained and removed to a proper disposal facility. BIO-4: Equipment Staging. Equipment, vehicles, and materials staged and stored in Caltrans right-of-way will be sited in previously paved or previously disturbed areas only and will avoid native vegetation. BIO-5: De-Watering Plan. For all bridges that cross jurisdictional drainages and are susceptible to running water, a de-watering/water control plan must be created and implemented in accordance with Caltrans Water Control Standard Specifications (Standard Specification 13-4.03G) if water is present or could be present

  • Countywide Airspace Usage
    A PPENDIX I Countywide Airspace Usage Riverside County is within one of the busiest and most complex sections of airspace in the United States, handling over 4.3 million operations annually. To better understand the magnitude of these op- erations and complexities of this system, Map 1 depicts Instrument Flight Rule (IFR) operations for the six busiest airports in the area for a 24-hour period on January 26, 1996. This exhibit does not depict operations from the 14 airports in Riverside County Airport Land Use Compatibility Plan update. AIRSPACE STRUCTURE Since the advent of aviation, nations have established procedures within their boundaries to regulate the use of airspace. Airspace is broadly classified as either “controlled” or “uncontrolled” in the United States. The difference between the two categories relates primarily to requirements for pilot qualifica- tions, ground-to-air communications, navigation and traffic services, and weather conditions. Six classes of airspace have been designated in the United States. Airspace designated as Class A, B, C, D, or E is considered controlled airspace. Aircraft operating within controlled airspace are subject to vary- ing requirements for positive air traffic control. The airspace in Riverside County, as illustrated on Map 2, is constantly occupied by aircraft arriving and departing from other airports in the region. Frequently, overflights experienced in communities near Riverside County airports are not the result of operations at nearby airports, but from aircraft us- ing airports outside Riverside County. After the preparation of this plan, additional approaches have been established for aircraft arriving at Los Angeles International Airport. These new approaches were not included as part of the map development process for this plan.

  • Cultural Resources
    Draft DRECP and EIR/EIS CHAPTER III.8. CULTURAL RESOURCES III.8 CULTURAL RESOURCES This chapter presents the environmental setting/affected environment for the Desert Renewable Energy Conservation Plan (DRECP) for cultural resources. More than 32,000 cultural resources are known in the Plan Area and occur in every existing environmental context, from mountain crests to dry lake beds, and include both surface and sub-surface deposits. Cultural resources are categorized as buildings, sites, structures, objects, and districts under both federal law (for the purposes of the National Environmental Policy Act [NEPA] and the National Historic Preservation Act [NHPA]) and under California state law (for the purposes of the California Environmental Quality Act [CEQA]). Historic properties are cultural resources included in, or eligible for inclusion in, the National Register of Historic Places (NRHP) maintained by the Secretary of the Interior and per the NRHP eligibility criteria (36 Code of Federal Regulations [CFR] 60.4). See Section III.8.1.1 for more information on federal regulations and historic properties. Historical resources are cultural resources that meet the criteria for listing on the California Register of Historical Resources (CRHR) (14 California Code of Regulations [CCR] Section 4850) or that meet other criteria specified in CEQA (see Section III.8.1.2). See Section III.8.1.2 for more information on state regulations and historical resources. This chapter discusses three types of cultural resources classified by their origins: prehistoric, ethnographic, and historic. Prehistoric cultural resources are associated with the human occupation and use of Cali- fornia prior to prolonged European contact.

The Bureau of Land Management (BLM) prepared the PAiFEIS in consultation with cooperating agencies, taking into account public comments received during the National Environmental Policy Act (NEPA) process. The proposed decision on the plan amendment would add the GSEP site to those identified in the current COCA Plan, as amended, for solar energy production. The preferred alternative on the GSEP is to approve the dry cooling alternative to the right-of-way grant applied for by Genesis Solar, LLC. This PAIFEIS for the GSEP has been developed in accordance with NEPA and the Federal Land Policy and Management Act of 1976. The PA is largely based on the preferred alternative in the Draft Resource Management Plan·AmendmentlDraft Environmentallmpact Statement (DRMP-AiDEIS), which was released on April 9, 2010. The PAIFEIS for the GSEP contains the proposed plan and project description, a summary of changes made between the DRMP·AlDEIS and PRMP-AiFEIS, an analysis of the impacts of the decisions, a summary ofwritten comments received during the public review period for the DRMP­ AlDEIS and responses to comments.

Holland, Ph.D. for State of California, The Resources Agency, Department of Fish and Game (October 1986) Codes revised by Thomas Oberbauer (February 1996) Revised and expanded by Meghan Kelly (August 2006) Further revised and reorganized by Jeremy Buegge (March 2008) March 2008 Suggested citation: Oberbauer, Thomas, Meghan Kelly, and Jeremy Buegge. March 2008. Draft Vegetation Communities of San Diego County. Based on “Preliminary Descriptions of the Terrestrial Natural Communities of California”, Robert F. Holland, Ph.D., October 1986. March 2008 Draft Vegetation Communities of San Diego County Introduction San Diego’s vegetation communities owe their diversity to the wide range of soil and climatic conditions found in the County. The County encompasses desert, mountainous and coastal conditions over a wide range of elevation, precipitation and temperature changes. These conditions provide niches for endemic species and a wide range of vegetation communities. San Diego County is home to over 200 plant and animal species that are federally listed as rare, endangered, or threatened. The preservation of this diversity of species and habitats is important for the health of ecosystem functions, and their economic and intrinsic values. In order to effectively classify the wide variety of vegetation communities found here, the framework developed by Robert Holland in 1986 has been added to and customized for San Diego County. To supplement the original Holland Code, additions were made by Thomas Oberbauer in 1996 to account for unique habitats found in San Diego and to account for artificial habitat features (i.e., 10,000 series).
